What is OGM? Is it related to OGG somehow? And what do I need to view it???

Ahhh yes, here I go again fiddling with something I know zip, zero about. I was surfing around on Pocket PC sites and I came across this website.

I saw a link to download the preview to LOTR Return of the King. (I have seen it by the way :D ) I was going to download it when I saw it was a OGM file. Does anyone know what that is? What do I need to play it? Is it somehow related to OGG?

Grin, I love trying new things :)

Never heard of it but assumed it had to do with ogg. I :google:d it and found this (http://cyrius.bunkus.org/ogmtools.html)

OGM is a video and audio wrapper format, like AVI. It is indeed related to OGG, which is just the audio part (OGG files are sometimes OGG Vorbis files, because they use Vorbis compression). The advantages of OGM over AVI include support for VBR audio (AVI can take VBR MP3, but often has problems with it) and support for subtitle streams (even multiple ones). To play OGM files on a PPC you will need to use PocketMVP, and on the desktop something like Zoom Player (http://www.inmatrix.com/). To create OGM files for PPC, use PocketDivxEncoder (http://divx.ppccool.com/langue.php?lang=EN) or VirtualDubMod (http://virtualdubmod.sourceforge.net/). (I recommend Pocket Divx Encoder—VirtualDubMod is really confusing to use with OGMs at first.)

One advantage of OGMs is that it can have chapters. It can retain the same chapters as the original DVD.
